The "waves school" will start on November 4 . It is intended for graduate students, post-docs, researchers, engineers or consultant that are dealing with ocean wave data of one form or another. The school will draw from the latest developments made possible by the IOWAGA, NOPP-waves, & Previmer, projects, and will benefit from the new (beta) release of the WAVEWATCH III (R) version 4 from NOAA/NCEP.


The program is designed in such a way that people that only use wave data and do not want to run a model can attend day 1 & 2 while the real brave geeks that actually want to install WAVEWATCH III and run the thing will be welcome to stay until late Friday.

  • Monday 4, 9-10 AM: Welcome, coffee, logistics, discussion of participants objectives (e-mail discussions before Monday 4 are welcome): what do you want to acheive / understand with wave data and models.
  • Monday 4, morning, starting at 10 AM (lectures)
basic principles of ocean waves: elevations, velocities pressure.... and spectra ( 1 hour: Fabrice Ardhuin)
different spectral wave parameters: what can be measured and what is usually measured ( 20': Fabrice Ardhuin)
short break (lunch ticket sales)
wave measurement databases: altimeter and SAR data, buoy data, seismic noise, IOWAGA & Previmer model databases
                                      ( 30':  Fabrice Ardhuin)                                                   
the NCEP hindcast and forecast database ( 30': Henrique Alves)
examples of ocean engineering applications: long term statistics ... ( 30': Michel Olagnon)
Lunch break 1 PM - 2 PM
  • Monday 4, afternon, starting at 2 PM (hands-on practical training)
Model and data file formats: ASCII & NetCDF, reading tools (M. Accensi)
using long wave data time series (??)
reading wave model output and altimeter data, performing simple error analysis on wave models
coffee break from 4 PM to 4:30 PM & Posters
comparing ocean wave model or buoy data and seismic noise records
closing at 6 PM.
  • Dinner somewhere ( downtown Brest, around 8 PM).
  • Tuesday 5: Physical parameterizations and numerics, 9 AM (lecture)
the wave action equation
parameterizations in wave models and impacts on various quantities: from Hs to air-sea fluxes. Why results from

this WW3 different can be different from that or that version of WAM or SWAN. So why do we have different wave models? (F. Ardhuin 1h50 hours).

forcing fields: quality of wind fields, validation datasets
coffee break
wave model numerics: principles (A. Roland. 1 hour)
wave model numerics: the dark side of limiters, SWAN's "renormalization" .... (A. Roland, 50 minutes)
  • Tuesday 5: Physical parameterizations and numerics. afternoon (hands-on practical training)
analysis of different model hindcasts and different model resolutions. (spatial, possibly spectral too).
evidence of discretization and numerical scheme effects on coastal wave model results
  • Wednesday 6, morning:
Basic information on installing and running WAVEWATCH III
desingning and optimizing unstructured grids
  • Wednesday 6, afternon (hands-on practical training)
the polymesh fun fair: grid generation for unstructured grids
  • Thursday 7, morning:
Running WW3 as a multi-grid system
grid generation for regular grids
  • Thursday 7, afternoon: (hands-on practical training)
more fun stuff (gridgen, polymesh ...)
  • Friday 8, morning: to be defined (possibly something more interactive on the different projects of the participants)
